To all whom it may concern:

Be it known that I, HERMAN WINTER, of the borough of Brooklyn, of thecity of New York, in the State of New York, have invented certain newand useful Improvements in Apparatuses for Making Stereotype- Plates, ofwhich the following is a specification, reference being had to theaccompanying drawings forming a part hereof.

In the use of stereotype plates with a curved cross-section, that isstereotype plates having a substantially semi-cylindrical shape, it isoften advantageous to have the plates comprise a segment of more than180 degrees or in other words to have the cylindrical plates greater inextent than that of a semicircle. For by such means it not only happensthat a wider range in the size of plates that can be manufactured by aparticular machine, is permitted, but the form of the plates whichcomprise a segment greater than 180 degrees, particularly adapts themfor use in certain kinds of presses.

Heretofore with a semi-cylindrical drag and a correspondingly shapedcope, which was adapted to be inserted into and withdrawn from the openside of the drag, no stereotype plates, as is obvious, could be madewith a curvature greater than 180 degrees.

It is accordingly one of the objects of the present invention to providean apparatus of this general character in which it will be possible tocast stereotype plates comprising a segment greater than 180 degrees.

Other objects of the invention are to improve such apparatuses indifferent details all of which will be referred to hereinafter and inconnection with the drawings in which a practical apparatus embodyingthe invention is shown.

In said drawings Figure l is a view in side elevation of this apparatus,Fig. 2 is a view in front elevation, Fig. 3 is a view in side elevationwith the casting box partly in section and shown in its verticalposition, Fig. 4 is a view in front elevation of the casting box showingthe two parts of the cope drawn together or collapsed, Figs. 5 and 6 aredetail sectional views of a portion of one of the clamps for securingthe cope to the drag,

. Figs- 7 and 8 are detail views of the head gage, and Fig. 9 is adetail broken view showing one of the pivoted side gages and the stripto which it is pivoted.

The casting box A, as usual, may be provided with trunnions a andpivoted upon a frame B, whereby it may assume a horizontal position forthe insertion of the matrix and for the removal of the finished plate ora vertical position for the casting of the plate. For holding thecasting box in a horizontal position, one or more bell crank lovers 1)may be provided pivoted to the frame B and means such as a foot press I)may also be provided to disengage the levers b from the casting box saidlevers being normally held in their engaging position by a spring 6Stops b and b are preferably placed upon the frame B so as to assist insupporting and steadying the casting box when it is in its horizontaland vertical positions respec tively.

The cope O of the casting box, is pivoted to the rear end of the drag atc and is r0- vided with a weight (Z and a cord (1 which latter issecured thereto and runs over a pulley 61 back of the casting box,whereby the cope can be conveniently manipulated upon its hinge by theoperator.

The segment comprised by the drag, as will be seen from Figs. 2 and 4,is somewhat greater than 180 degrees, the precise extent, however, over180 degrees being unimportant. In order to permit the cope to be readilyinserted into and withdrawn from the opening in the upper side of thedrag, said cope is split lengthwise and thus comprises two parts orsides, 0 and c, which are arranged so as to be readily collapsed andexpanded, as required. Thus, when the cope is collapsed, it may bereadily moved into and out of the drag, and after the cope has beenmoved into the drag it may be expanded so as to occu y the properposition with reference to the si es of the drag and the matrix m forcasting. For this purpose the two sides of the cope c and c arepreferably pivoted, as shown in Fig. 3, to a central support 0 for thecope, said support being ivoted or hinged at c, as already stated andhaving toward its forward end a cross bar 0 which, through means such asadjustable screws 0 is supported on the drag, near the forward endthereof. As

' clamping.

shown the cope support 0 has two pins 0 upon which the sides 0 and c arepivoted.

In order to expand and collapse the two sides of the cope, they may beconnected at the top by means of links 6 to a crank 6 fast upon a shaft6 rotatable in the cope support, a lever e being provided whereby theshaft 6 may be rotated at will and the cope sides expanded or contractedas the case may be. Preferably the shaft 6 extends substantially thelength of the cope and is connected to the sides of the cope in themanner described above, at both ends thereof.

When the cope has been inserted into the drag and is extended as justdescribed, it is firmly secured to the drag by clamps f, of which thereare preferably four, one on each side near the front and near the rearof the casting box. Each of these clamps is mounted loosely on a shaft fwhich has an eccentric bearing or pivot f to which a handle f issecured. The clamps are adapted to engage lugs f 4 on the cope, and whenthey have been brought to engage said lugs, the handles are moved so asto rotate the shafts f u on their eccentric pivots whereby said 0 ampsare tightened against the lugs. j, Fig. 1 shows the position of theclamps f and the handles f before the clamping and Fig. 2 the positionof these parts after the Furthermore each of the clamps is provided witha spring f 5 which encircles its pivot f and one end of which springengages the clamp while the other end engages the shaft upon which theclamp is pivoted. The spring thus normally tends to hold the clamp backfrom its lug in a substantially vertical position, as shown in Fig. 4,whereby it will not be in the way as the cope is moved into and drawnout of the opening in the top of the drag.

The apparatus is provided, as usual, with a head gage g, which maycomprise a band with conveniently formed handles and adapted to besprung into the rear end or head of the drag, and side gages h, which inthe present 1 spring clamp handle is provided.

case are pivoted to a long strip h, which is screwed onto either side ofthe drag. The matrix is secured in the drag, as usual, by means of thegages, and the pivoting of the side gages makes the operatlon ofsecuring and releasing the matrix particularly convenient.

In addition to the head and side gages there is provided what will bereferred to as a split gage, which in the present case, consists of along bar or strip 76 adapted to fit in tightly and in a lengthwiseposition between the cope C and the matrix m. This gage is providedso'that plates of different sizes may be cast as desired. In order tohold this gage in position and to move it about from one part of thecasting box to another pat, 3

a1 spring clamp handle may comprise an extension on the bar or strip 7cprojecting somewhat beyond the end of the casting box and a member 76pivoted thereto with a projection k upon the inner end thereof whichfits in a small groove behind a shoulder k which runs around the frontend of the drag. A spring k is provided between the member 7c and theextension of the strip 7c whereby the projection 76 is held tightly insaid groove. When it is desired to change the position of the split gagein the casting box the handle is grasped by the operator and the member7c is moved against the action of the spring k thus Withdrawing theprojection W from the groove behind the shoulder it. When the gage hasbeen properly adjusted, the operator lets go the handle and the gage isautomatically fastened, as will be clear from Fig. 3 of the drawing. Itwill be understood that the casting operation is performed when thecasting-box is in its vertical position, as shown in Fig. 3, 'and afterthe plate has been cast the box is tilted to its horizontal position, asshown in Fig. 1, the cope being collapsed and moved out of the drag, andthe plate removed through the front end of the drag, or,

by rotatingit about one-quarter, it may be lifted out through theopening in the top of the drag.

Various changes may be made in the construction of the apparatus hereinshown and described without departing from the inven tion, and the scopeof the invention is accordingly not limited to the embodiment of theimprovements herein specifically referred to.
